I'd like to put the bpo source (the python rewrite version) under the AGPLv3, since bpo is a web application.
Both versions of the Affero GPL were designed to close a perceived application service provider (ASP) loophole in the ordinary GPL, where, by using but not distributing the software, the copyleft provisions are not triggered. Each version differs from the version of the GNU GPL on which it is based in having an added provision addressing use of software over a computer network. This provision requires that the full source code be made available to any network user of the AGPL-licensed work, typically a web application.
@MartijnBraam: you're the only one who wrote code in that repository, besides myself. Is this fine with you?
